Proportional Directional Valve 4WRDE25V1-220L-6X/MXYWG/24A5 - Bosch Rexroth R901518465

An axis that must resolve well in slow motion gains nothing from an oversized nominal curve. The 4WRDE25V1-220L-6X/MXYWG/24A5 is therefore rated at 220 l/min, while the size 25 body still passes up to 870 l/min.

Benefits

• 220 l/min nominal flow gives finer resolution over the same signal span than the 350 l/min curve.
• Up to 870 l/min maximum flow remains available, the size 25 cross section is not reduced.
• 350 bar operating pressure across 4 ports with 3 switching positions, symbol V1.
• On-board electronics with ±10 V command value, 24 VDC supply, 7-pole connector (6 + PE) to EN 175201-804.
• External pilot oil routing on supply as well as return, 18.95 kg, NBR seals.

Application

The valve suits axes that mostly run in the middle of their range and call for full throughput only occasionally. On test rigs as well as forming presses the smaller nominal stage improves positioning accuracy without changing the interface. Subplate mounting to ISO 4401-08-08-0-05 keeps it interchangeable with the 350 l/min version.
